FarmRover

Autonomous Fertiliser Sprayer — Powered by Air & Sunlight

Active R&D — Prototype Phase

Overview

FarmRover is a self-driving fertiliser sprayer that doesn't just apply fertiliser — it makes its own. Using a solar-powered plasma reactor, FarmRover pulls nitrogen directly from the atmosphere and converts it into nitrate fertiliser on-the-go. No bags of chemicals. No supply chains. Just air, sunlight, and science. It's fertiliser production and application in one autonomous machine, built to operate on the small, fragmented farms that feed most of Africa.

Nitrogen From Air

At the heart of FarmRover is a miniaturised plasma-catalytic reactor that splits atmospheric nitrogen (N₂) and combines it with oxygen and water to produce dilute nitrate solution — a form plants can absorb directly. This eliminates the need for the Haber-Bosch process and its massive energy and fossil fuel requirements.

Atmospheric nitrogen fixation using non-thermal plasma technology

Solar-powered reactor — zero fossil fuel input, zero carbon emissions

Produces dilute calcium nitrate solution ready for immediate application

Continuous synthesis while the rover is operating in the field

No need to purchase, transport, or store chemical fertiliser bags

Autonomous Precision Spraying

FarmRover navigates autonomously across any terrain, applying its self-made fertiliser exactly where crops need it most — using real-time sensor data and GPS-guided path planning.

Multi-terrain navigation: handles muddy, rocky, and uneven surfaces

GPS-guided waypoint navigation with centimetre-level precision

Variable-rate application based on crop health and soil conditions

Onboard LIDAR and camera sensors for obstacle avoidance

Remote monitoring and mission control via smartphone app

Why It Matters

Fertiliser is the single biggest expense for smallholder farmers, and supply chains are unreliable across rural Africa. FarmRover removes fertiliser cost from the equation entirely — making crop nutrition practically free after the initial machine investment.

Eliminates fertiliser purchase costs — the biggest input expense for farmers

Breaks dependence on fragile, expensive fertiliser supply chains

Enables precision application — up to 40% less waste than manual spreading

Solar-powered operation means near-zero running costs

Designed for community-level ownership and cooperative models
